-Main Application: This is the central interface
where, the user may view data elements such as
Shape files and Grids and the Core Components
-The components which operate underneath. The
three main components are:
1. MapWin GIS, which is an ActiveX control
which may be placed into any project in any
programming language that supports ActiveX.
This is the main map component - if the user
wants to write a program that displayed shape
data, for example, the user could use this control
for the display portion of the user’s program.
2. MapWin Interfaces, which is also called the
"Plug-in Interface". It is a dll file which will
allow the user to write the user’s own plug-ins to
the main application. This may be done from any
programming Language which supports the
creation and use of Microsoft .NET 2.0 Dynamic
Link Libraries (dlls).
3. MapWin GeoProc, which is a .NET library of
geoprocessing functions, including tools for
managing projections, clipping and buffering.
This Library is under very active development
with new capabilities appearing Often.
Petrel Software (2009.1): Petrel is a subsurface
interpretation and modeling that allows building and
updating reliable subsurface models. Geophysicists,
geologists, and reservoir engineers can move across
domains, rather than applications, through the Petrel
integrated toolkit. The software objectives are to: (a)
import and edit input data, (b) perform seismic
visualization and interpretation, (c) perform well
correlation, (d) use the pillar gridding process to
create 3D grids, (e) generate horizons, (f) perform
geometrical modeling, (g) calculate volumes and (h)
plot results.
Program Petrel deals with the following aspects:
1. Petrel Geology and Geological Modeling
2. Petrel Geophysical Software
3. Petrel Reservoir Engineering
4. Petrel Drilling
The relation between PETREL and GIS is
presented in Importing and Exporting files.
Petrel Software is a Schlumberger owned Windows
PC software application intended to aggregate oil
reservoir data from multiple sources. It permits the
user to understand seismic data, achieve well
correlation, construct reservoir models suitable for
simulation, offer and envisage simulation results,
estimate volumes, generate maps and devise
development strategies to enhance reservoir
exploitation. Moreover, it addresses the need for a
single application able to support the "seismic- to-
simulation" workflow, and minimize the need for a
multitude of highly specialized tools. By carrying
the whole workflow into a single application where
risk and ambiguity can be evaluated during the life
of the reservoir.
Petrel was created specifically for PCs and the
Windows OS; it was commercially available in
1998. It has a familiar Microsoft like interface, to
enable less experienced user to follow. Techno guide
made 3D geologic modeling more accessible to all
subsurface technical staff, even those without
specialist training. It has the following Modules:
Geology and Geological for reservoirs, Geophysics
for seismic 2D & 3D interpretation and Reservoir
Engineering and Utility System.
Relation between Petrel & GIS:
Petrel users can import a range of standard GIS data
for display and use in operations in their 2D and 3D
windows, as well as export Petrel data (Figures 1
and 2) types for use in GIS maps and workflows.
The user is not limited to only local data through
Shapefiles, but can get into common corporate data
from the user’s Intranet via Import and Export GIS
Keys. Petrel-compliant coordinate conversion
during import process assures proper alignment and
display. Moreover, it can use attribute data for
presentation control and computation.
Data integration is not limited to just points, lines
and polygons. Associated attribute data is also
imported and can be employed in various ways such
as for labeling, presentation control, or in Petrel
workflows and computations (see Figure 3).
Share Surfaces and Grids between Petrel and
ArcGIS can be illustrated by Figure 4. Thus the user
can quickly incorporate asset-level data into regional
study maps to provide new levels of understanding
and access to such information for others across the
organization.
Study Area:
The Study Area is Al-Azraq Oasis which is located
in the desert in the east part of Jordan (area of 12
square kilometers). Figure 5 presents a GIS map for
the Study Area.
The objective here is the development of an
OSGIS (using MapWindow) and the integration of
petrel software to import information to include in
the OSGIS about the oasis (water body reservoir).
This presents an application to consider when using
OSGIS.
